BER-POSITIONING DEVICE FOR TYPE-WRITERS.

Specification of Letters Patent.

Patented Aug. 25, 1914.

Application filed January 30. 1913. Serial No. 745,123.

To all 2071 am it may com-( m Be it known that I, CLINTON D. PALMER, i2. citizen of the United States, residing at i'lhicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Paper-Positioning Devices for Type-\Vriters, of which the following is a specification.

This invention relates to typewriting machines and contemplates an improved means for uniformly positioning the paper on the r-aten. v The embodiment of the invention shown in the drawings is intended more particularly for typewriting on cards, such, for example. as are used in card indexes and other card systems. It should be understood, however that the invention is not limited to sueh use. In typewriting on cards, it is often desirable that the first line of writing should be spaced at a uniform distance from the tops of the cards, this being particularly true when the cards are ruled, or when they are printed and have blank spaces left to be filled in on the typewriter.

One of the objcrts of this invention is to provide improved means for stopping the paper, so that the forward edge thereof shall occupy a definite or uniform position with reference to the writing line.

Another object is to provide a stopping means the use of which shall require no attention on the part of the operator.

A further object is to provide paper-positioning means which may be manufactured separately as an attachment and may he conreniently applied toexistingmachines.

The purposes and advantages of the 111- vention will be further understood from the following detailed description.

In theaccompanying drawings. Figure 1 a frag-mental front elevation of a typewritinu iuachine embodying my improvements. lrig. 2 is a fragmental front elevation of the stop means showing the parts in a different position from Fig. 1. Fig. 3 is a transverse vertical sectional view through the carriage and adjacent parts, taken on the line 3 2-3 of Fig. 1. Fig. 4 is a fragmentary sectional view similar to 'Fig. 3. but showing the parts in a different osition. Fig. 5 is a vertical sectional view of the welllmown Monarch nnu-hiue. showing my invention applied thereto.

In the present instance, I have illustrated my invention as embodied in an attachment which is built separate from the machine and is arranged to be applied to any of the standard visible typewriters. It will be understood, however, that my improvements may be built as a permanent part of the typewriter, if desired.

The means for guiding the cards into uniform position on the platen comprises a member 5 having two like passage-ways or chutes 6 and l therein, the rear passage-way being of a length to receive the card when inserted sidewise into the machine, and the forward passageway being adapted to receive the card when inserted endwise. The end walls of the passage-ways are preferably flared or tapered at their receiving ends, as clearly shown in Fig. 1. The passage-ways also are preferably tapered from top to bottom, as shown in Fig. 3. If desired, a portion of the rear wall of the member may be cut away, as at 8 to facilitate grasping a card inserted into either of the passage-Ways. \Vhen my invention is embodied in the form of an attachment, the member 5 is mounted upon the paper shelf 9 of the typewriter. The member 5 may be ecured to the paper shelf by means such as screws 10 passing through the ends of the member into said shelf and having nuts th eaded on their rear ends. As the card leaves the lower end, of the guide member 5, it passes between the platen 11 and the curved guide plate 12, being held against the platen by spring-pressed rollers 13 and 1% in the usual way.

In order to stop the advancing edge of the card at a uniform distance from the writing line on the platen, I provide the following means. A bracket 15 is secured to the frame 16 of the typewriter in any suitable way. as by means of screws or bolts 11' passing through said bracket and into the U-shape portion of the typewriter frame which lies just beneath the platen. The bracket 15 comprises a base or attaching portion 18 from one end of which a finger l5 rises. the upper end of said finger lying in front of the platen 11 and serving to guide the card and hold it close to the platen. The bracket 1?; extends upwardly from the other and o thc attarhin; portion 19 and has a rclatiwly \riilc upper end 90. .i stop plate 31 has journals '22 pivoted in outwardly extending cars 23 on the end porl tion 20. The upper edge of said step late has a rearwardly extending flange or lip :24 arranged to be moved toward the platen and to be engaged by the advancing edge of the card.

From an inspection of Fig. 1, it will be noted that the finger l9 and the portion 20 lie at opposite sides of the ribbon-vibrating device 25 and behind the ribbon 26, so that the feeding and vibrating of the ribbon is not interfered with. Said parts 19 and 20 act to hold the card close to the platen at opposite sides of the striking point of the type.

A lever 27 is pivoted between its ends at 28 on the linger .19, one end of said lever having an angular arm 29 extending upwardly toward the stop-plate 21. Preferably, the arm 29 has a slot 30 therein through which a guide screw 31 extends, said screw being threaded in the bracket 15. The upper end f the arm 27 is beveled as at 32, and is arranged to engage a downwardly extending lug 0n the stop plate 21. The lower end of said lug is beveled or bent outwi'iriilly, so that when the arm 29 is raised the beveled end thereof will move the lug outwardly and force the lip 524- on the stop plate inn; he path of a card. A leaf spring 3.4, find to the bracket portion 20, engages the stop plate and tends t hold the lip it out of the path of the card. A coiled spring 35, secured at one end to the lever 27 and at its other end to the base 18 of the l'HMhUl tends to pull the arm 29 downwarllly.

The opposite end of the lever 27 has a cam portion :1; thereon comprising two inclined sid s and a t p or rest portion. A downw ardl y extending arm 37 is fixed on one end at the carriage frame 38, the lower end of said arm being arranged to ride up on the in line of the rain 36 as the cariage is movul to starting position, and to rest on the [up of the 'cam when the carriage is in its iuilial position, so that the arm 29 on the lever 27 will be forced upwardly to hold the stop flange or lip 2 in position to stop the card as it is led by the l'utl ting platen.

The length ol the "Hill arm 27" of the lever ET is preferably made such that the top of the rain will be in line with the adjacent end wall of the longer passage-way in the guide member 5. ill carriagestop de- \lrQ lLlll mar nal s op) on the-typewriter will he H m wooed that the arm 37 will la-nr on llu l p oi" the cam 30 when the carriae'c i in ll initial or starting position.

Fig. 5 illustrates the mechanism of the Meuiir h lvncwl'itcr substantially as showi in Patent Yo. 921L373. dated Oct. ll. lfilll As. tXplulii'u'l in said patent, 4i is a universal bar that uudi-rlies the hey lovers 8. Said bar is secured to arms 42 which are pivoted at as, the parts 41, and 43 form mg a universal frame from which an arm ll illOJGCtS rearwardly. An upwardly ex tending link 47 connects the arms 46 to the forwardly extending arm of a dog-rocker 50 pivoted at 51. The dog-rocker carries the feed dogs 6 Each key lever has a sub lever 11 pivoted thereto at 12. Each sub lever is pivoted to the framework at 20". The upper end of each sub-lever is pivoted at 13 to a draw-link 14 which is connected to one of the type bars 16".

In use, a card is dropped into one of the passage-ways in the guide member 5 and the platen 11 given a rapid whirl,'the operator paying no attention to the extent of the rotation. As soon as the advancing edge of the card strikes the rearwardly-projecting stop lip 2%, further advance of the card will be checked, the pressure of the paper-feed rolls 1% and 15: being so adjusted that when the advancing edge of the card strikes the lip 24, the platen slips on the card until the platen comes to rest. As the first character is written on the card, the escapemont mechanism of the typewriter permits the carriage to travclto the left in the usual way, so that the arm 37 will move off the cam 36, thereby permitting the spring 35 to draw the 0pposite end of the lever 27 downwardly and release the stop plate 21 which then moves into inoperative position. Thus as soon as the first character has been written, the card may, if desired, be freely fed upwardly by rotating the platen through the line space mechanism in the usual Way. A depression of the space bar likewise throws out the line-stop 24.

lVhen matter is tobe written on the card along the other dimension thereof, the card is dropped into the other passageway in the guide-member 5, and the platen given a spin to carry the card to writing position.

The two passageways 6 and 7 are so arranged relatively to each other that one serves as a marginal stop for one margin of a card, while the other passageway serves as a marginal stop for another margin of the same card.

It will be seen that my invention provides means for positioning a card with respect to its margins, and in definite relation to the writing line, without requiring any attention on the part 'if the operator other than to drop the card into the guide and give the platen a spin. Thus much time may he saved inthe'production of card records and the like.

\Vhile I ha e herein described my invention in considerable detail. I realize that many changes may be made by those skilled in the art. without departing from the scope of the appended claims, and I therefore do not limit any invention to the llx'fltt construction herein disclosed.
